Such antibodies, patterned after ones made in rare people who are able to hold HIV infection in check, might someday benefit other patients chronically infected with HIV, say the research teams. The antibodies are broadly neutralizing, meaning they can hit diverse forms of the virus. That makes them more potent than antibo...
